Systems and methods for continuous data protection comprising storage of completed I / O requests intercepted from an I / O stream using touch points
By intercepting and replicating virtual disk I/O streams to form a snapshot-log chain, the system addresses the limitations of snapshot-based backup, achieving near-zero RPOs and minimizing user impact.

AI Technical Summary
Technical Problem
Snapshot-based backup and recovery technologies for virtual machines (VMs) result in recovery point objectives (RPOs) of tens of minutes, impacting user experience due to the expense and frequency limitations of taking snapshots.
Method used
Intercepting virtual disk I/O streams at near-real-time to replicate data to a backup site, forming a recoverable snapshot-log chain, and optimizing RPO to seconds by managing I/O logs and snapshots.
Benefits of technology
Achieves near-zero recovery point objectives by minimizing user impact and reducing snapshot frequency to near-real-time data replication.

Abstract
Example embodiments relate generally to systems and methods for continuous data protection (CDP) and more specifically to an input and output (I / O) filtering framework and log management system to seek a near-zero recovery point objective (RPO).
